“How often have I said to you that when you have eliminated the impossible, whate…” — Arthur Conan Doyle

As Cuvier could correctly describe a whole animal by the contemplation of a single bone, so the observer who has thoroughly understood one link in a series of incidents should be able to accurately state all the other ones, both before and after.

It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth.

The most difficult crime to track is the one which is purposeless.

You will, I am sure, agree with me that... if page 534 only finds us in the second chapter, the length of the first one must have been really intolerable.
